The invention provides a terminal device having a main body, a sounding assembly and a cover plate. The sounding assembly includes a housing and a sounding body. The housing has an accommodating groove and a first sounding channel. The main body has a second sounding channel and a first sound emitting hole. The cover plate has a first through hole. When the sounding assembly is located at the first position, the sound is propagated to the outside through the first through hole, the second sounding channel and the first sound emitting hole in sequence. When the sounding assembly is located at the second position, the sound is propagated to the outside through the first sounding channel. The present invention improves the problem that the sound effect is affected by airflow sound, piano sound, etc., generated by the terminal device in the speaker mode.
